270 REPORTS ON INVESTIGATIONS AND PROJECTS. 



the magnetic elements on land at Norfolk (Virginia) , San Juan and 

 Vieques (Porto Rico), and took part in the sea work. Toward the 

 end of May he entered upon a trip through the Windward and Lee- 

 ward islands and determined the magnetic elements at the following 

 stations, at many of which observations had previously been made : 

 Charlotte Amelia (St. Thomas), Phillipsburg (St. Martin), Crocus 

 Bay (Anguilla), Christiansted (St. Croix), Basse Terre (St. Chris- 

 topher), Charlestown (Nevis), St. Johns (Antigua), Codrington 

 (Barbuda), Plymouth (Montserrat), Basse Terre, Point a Pitre, and 

 L,e Moule (Guadeloupe), Grand Bourg (Marie Gallante), Roseau 

 (Dominica), Fort de France (Martinique), Port Castries (St. Lucia), 

 Bridgetown (Barbados), Kingstown (St. Vincent), St. George (Gre- 

 nada), Port of Spain, San Fernando, and Sangre Grande (Trinidad), 

 Scarboro (Tobago), and Caracas (Venezuela). At San Fernando 

 (Trinidad) he carried out extensive observations of dip in different 

 azimuths for the purpose of discussing inequalities of pivots of 

 needles. 



He has thus satisfactorily completed, without mishap or delay, 

 a piece of work requiring special care, good judgment, and skill. 

 All of these stations have been permanently marked to serve for 

 future use by the department, as well as by others. 



Mr. G. Heimbrod, formerly surveyor of Suva, Fiji Islands, entered 

 the employ of the department in September. After assisting Dr. 

 Franz Linke, in charge of the German magnetic observatory at 

 Apia, Samoa, and securing the necessary experience in magnetic 

 and electrical work, he will be engaged in determining the magnetic 

 elements on various islands in the South Pacific. 



Definite arrangements are furthermore being perfected for secur- 

 ing in the near future observations along the coasts in Canada, 

 Mexico, Central American countries, South America, and China 

 while the oceanic survey is progressing. 



The work in China will be conducted by Prof. Charles K. Edmunds, 

 Ph. D. (Johns Hopkins University), who at present is professor of 

 physics and of electrical engineering in the Christian College at 

 Macao, China. He has already secured the necessary experience in 

 magnetic work, as he was previously in the service of the Coast and 

 Geodetic Survey as a magnetic observer. He is now engaged in the 

 formulation of the plans in cooperation with Father J. de Moidrey, 



director of the Zi-ka-wei Observatory. 



In connection with the eclipse work, elsewhere related, important 

 secular variation and distribution data have also been secured in 

 Canada, Newfoundland, and Labrador.
